On Monday the official Chelsea website catches up with the expert summariser from the club's radio partner, BBC London 94.9, for analysis of the weekend's game.

Former Blues favourite Clive Walker was the man at the Bridge for Saturday's victory over the champions. He saw a Ferguson game-plan that nearly paid off, but happily didn't.

When two big sides come up against each other, people expect fireworks time and time again. That doesn't always happen. This was a tight affair between arguably the two best sides in the league but it was a performance not up to the highest standard of either side. The longer the game went on you felt that if one goal was going to be scored, it was going to be the winner. Both sides had opportunities to do that and fortunately, John Terry, or Nicolas Anelka, was there to head the ball home.

Man United's change in formation was more to do with the personnel they had available than concerns about the strength of the Chelsea midfield I believe. Without Ferdinand and Vidic, Alex Ferguson's worry would have been about the two central defenders with Drogba and Anelka up against them. So he needed to protect them and sticking three central midfielders in front of them gave that protection. Wayne Rooney was terrific for Man United and with more support up front for him, he might have given Chelsea more problem.

With the players Ferguson had available, it was a question of getting anything out of the game. We all know it is long season and I guess he would have looked at this game as not essential to who is going to win the title but it was important that Man United didn't fall too far behind Chelsea. Unfortunately for him, Chelsea scored but the game plan almost worked for him.

You have to give Wes Brown and Jonny Evans some credit, they handled Drogba very well. Didier wasn't up to his usual high standards. At times he was trying to do things that he does against weaker opposition and they come off. Against better opposition he can't do that and has to look at the game slightly differently. Ferguson will be happy with that but it was also a case of Chelsea not really imposing themselves on the visitors.

Chelsea didn't have much time on the ball. The Man United back four pushed very high because they felt we were hoping to play the ball into feet, and might play a few diagonal balls into Drogba, but Chelsea weren't going to really hurt them in behind. They felt they could play a high line, squeeze play, pack the midfield which was helped by the amount of bodies they had in there, and stifle us and stop us from playing - and it worked to a degree, although it wasn't pretty or particularly enjoyable to watch.

Riccy Carvalho was excellent and Nicolas Anelka did very well. There were a lot of times first half when Anelka dropped deeper and the fans don't like to see him that deep but in this game, it was important he got on the ball and he did that in good areas and asked questions.

The goal may have come about a bit fortuitously, the free-kick may not have been given, but you take your little bit of luck that sometimes makes champions. Man United had luck with the challenge by Evans on Drogba. The game did get feisty at times, there were some hard challenges going in plus shirt-pulling and elbows, and it was a tough game for the referee who handled it reasonably well. He made one or two poor decisions with a couple of bookings but essentially tried to keep the game going.

On a day when it is tight like that, Chelsea may need to look for more alternatives. The substitutions were like for like with one or two personnel moved around. Joe Cole coming on in a central area didn't change it and he could have come on in a different formation, maybe a 4-3-3 at that particular stage, which would have been a brave move. But then again you understand the two managers. With 20 minutes to go you can imagine they were thinking it would be lovely to win this game and we might try a change of personnel, but it is working in that neither team is giving anything away, so you understand the caution. Against one of the big four you can accept it.
